This study reports on a new integrated valorization alternative for extracted olive pomace (EOP) by recovering polyphenols as high-value compounds and the subsequent anaerobic digestion of the remaining dephenolized fraction for energy production. The average polyphenol extraction rate was 22.10 kg GAE t^-1 EOP and the subsequent optimum methane production from the remaining dephenolized fraction (278 L CH₄ kg VS^-1 d^-1) occurred at organic loading rate (OLR) 2.48 g VS L^-1 d^-1 and 24 d hydraulic retention time (HRT). The study also reports on the preliminary economic feasibility study and the sensitivity analysis to valorize 1,500 t EOP y^-1 under biorefinery concept. The calculated net present value (NPV) and internal return rate (IRR) were €1,996,856 and 58%, respectively. The sensitivity analysis concluded that the minimum sales volume of hydroxytyrosol (HT) extract and the sale price per mass are by far the most significant factors that might influence the overall economic feasibility of the proposed EOP valorization plant.

这项研究报告了通过提取多酚作为高价值化合物并随后厌氧消化剩余的脱酚馏分以产生能量的方法，对提取的橄榄果渣（EOP）提出了一种新的综合增值方法。平均多酚提取率为22.10 kg GAE t ^-1 EOP，随后在有机负荷率（OLR）为2.48 g VS L-的情况下，由剩余的脱酚馏分（278 L CH ₄ kg VS ^-1 d ^-1）产生最佳甲烷^{。 1} d ^-1和24 d的液压保持时间（HRT）。该研究还报告了初步经济可行性研究和对1,500 t EOP y ^-1计价的敏感性分析。在生物炼制概念下。计算得出的净现值（NPV）和内部收益率（IRR）分别为1,996,856欧元和58％。敏感性分析得出的结论是，到目前为止，羟基酪醇（HT）提取物的最小销售量和每质量的销售价格是可能影响拟议中的EOP增值装置总体经济可行性的最重要因素。
